simple.... southpaw's have clear advantages especially in defence.... no two southpaws fight the same, they're difficult to prepare for and they're hard to hit.... whitaker's claim to greatness was his defence.... but he's no pep, locche, mayweather. great southpaws are always overrated, whether that be calzaghe, hagler, whitaker, winky wright, pacquiao - if any of those guys would have been orthodox fighters their careers would have been far from memorable because they would have lost far more often.
